giocare posted... Do you have to kill all the mages fast enough or is there some other trick to this boss?
What I did in the begining of the fight. I took one mage down to low health while the other was trying to heal him but they keep knocking them selfs down.. so that distracted those 2. Then I casted unholy or w/e its called 3 times and fire once right at the guy peddling on the bike. Once he died the big guy came. Just hide behind the platform on the left and cast ur beam with ice and lighting at the mages
Easy mode - As soon as the fight starts, run behind the machine. The warlocks are too stupid to go around to get you. Two fully charged 5-earth rocks will end the first phase.
For the second part, shield like crazy. I think the regular guys keep respawning, so you have to kill the boss with the other two. They can combine their lightning/arcane beams for terrifying amounts of damage, so keep shielded to reflect that. Keep pounding on the main guy with whatever you like and he'll eventually fall. I used a 5-water aoe to make everyone wet, followed by an arcane-cold beam to freeze for the kill.
